Transformation of Air Pollutantsharm to a target whether ecosystems, material, man, or ultimately climate. Urban air pollution arises from the competition between emission processes which force up pollutant concentrations and dispersion, advection and deposition processes which reduce and remove them. However, not all urban air po

Regional/Mesoscale Models a given region, they influence the ventilation and thereby the air quality in the area. The most important mesoscale features are circulations exhibiting a diurnal cycle. To such circulation types belong land-sea breezes, internal boundary layers, up-slopes, down-slopes and drainage flows, as well

Street Scale Modelss is limited by the presence of buildings flanking the street. Moreover, we are dealing here with pollution phenomena that take place in the immediate vicinity of the source, the car traffic. Therefore modelling of this pollution must account for micro-scale processes, i.e. a scale that is much smal

Wind Tunnel Experimentshe atmospheric boundary layer on a small geometric scale, typically between 1/100. and 1/1000. of the real world. In the previous chapters, numerical models were grouped into different classes depending on the scales they are applied to. Physical modelling is mainly applied to the scale of street ca

Book 1998year 2000 nearly half of the world‘s population will live in urban areas. Air pollution has always been one of the major nuisances of urban living, but in recent decades the sources of pollution have changed in importance in most of the industrialised world. Earlier they were dominated by individual
